Early 1970's scheme:
ULAS Chipmunk from White Waltham on Summer Camp at RAF Newton in 1972. WK518 was also on the sqn's strength at the time and would have had the same colour scheme.
Those were
such fun days! But little did we know how the RAF would be decimated over the ensuing 40 years....
Nowadays there's no RAF Newton, no RAF presence at White Waltham and UASs cannot even afford to detach for Summer Camps.
